Description

Carbinol stove

The utility model is that a kind of making enters the pre-heat catalysis of methyl alcohol that transforms the chamber, penetrates the methyl alcohol kitchen range of gas fuel combustion, belongs to liquid fuel and evaporates in the combustion zone, and its evaporated fuel has the burner of chemical conversion.

Kitchen range are widely used, and use more popular with gas range especially.Usually, gas range can be divided into by the kind of coal gas: artificial coal gas kitchen range, natural gas range, liquefied petroleum gas stove and be applicable to the kitchen range of two or more coal gas.The used fuel of gas range is gaseous fuel, and these fuel all are industrial chemicals, and is very in short supply.In order to develop more fuel, particularly liquid fuel, various liquid fuel cooking range sequential use are as force ventilation oil dripping stove, rotary-cup type oil range, low-pressure air atomized fuel kitchen range or the like.Behind the middle nineteen seventies, the vaporization diesel range has obtained using and development in the naval vessel of China, hotel, the catering trade.This kitchen range to fuel preheating and vaporization, tend to reach perfection burning before fuel combustion, are a kind of kitchen range preferably.Chinese patent CN87201005[low noise jet absorption type vaporization diesel range] be exactly a kind of more advanced vaporization diesel range.Be characterized in heavy wall burning bowl, be drilled with the combustion gas sound proof housing of sound attenuation hole and the shower nozzle that is threaded with housing around in the cannelure of bowl, placing.Compressed air injection fuel oil is from the vaporific ejection of nozzle, and preheating and mixing in heavy wall burning bowl are vaporized oil gas and eliminate the noise through the combustion gas sound proof housing again, make mist of oil before burning, reach vapor state, with the abundant mixed combustion of air, thereby burning is more perfect, and noise obviously reduces.Yet this kitchen range but can not make the reaction of fuel generation catalytic conversion, and more inconvenient employing methyl alcohol acts as a fuel and burns.And methyl alcohol is as a kind of secondary energy sources, and wide material sources are a kind of rather important fuel.For this reason, after research for many years, the utility model provides a kind of methyl alcohol special stove that is mixed into fuel with the first alcohol and water.

The purpose of this utility model is to select pipeline, conversion chamber, the shower nozzle of catalysis material platinum or nickel or aluminium or copper production kitchen range for use; For conversion chamber and the design that approaches flat can make flare be ejected into the shower nozzle that transforms the place, chamber, continue to keep voluntarily the catalytic reaction temperature that transforms the chamber according to hydromechanical thin-wall effect design section, logical with the gentle smoothness of vaporization, catalyzed conversion of realization methyl alcohol.Select pipe, casing coupling joint and the filter of thin straight warp for use, to avoid the negative pressure recoil in the system or to block.Shower nozzle peripheral hardware tray is in order to hold pilot fuel, to prevent that methyl alcohol is accidental excessive.Thereby manufacture the methyl alcohol special stove.

Methyl alcohol mixed liquor fluid fuel and stove that the utility model contains 80% water by liquid reserve tank, are at most formed.Stove is made of filter, single-pass or multiple-way valve or joint, gas flow regulating valve, conversion combustion chamber, conversion chamber, shower nozzle, pallet, impregnator, igniter, bell, adjustable air regulator, kitchen range support and pipeline.Wherein, liquid fuel is preferably the mixed fuel of the methyl alcohol that contains 20-50% water.But switch, charging valve that fluid injection or discharge opeing are arranged on the liquid reserve tank.Can in the liquid reserve tank that is perfused with liquid fuel, fill kilograms per centimeter by valve with 0.2-0.5 ²Air pressure is so that liquid fuel can be pressed into woven hose after switch opens.Be equipped with before total inlet on the stove and be convenient to the filter dismantling, clean, filter connects the import of single-pass or multiple-way valve (or joint), and the outlet of single-pass or multiple-way valve (or joint) connects single kitchen range eye or many kitchen ranges eye.The thin pipe of directly making through platinum or nickel or aluminium or copper or other catalysis material that connects the kitchen range eye is connected on the entrance point that transforms the chamber by the casing coupling joint.Transforming the chamber uses less than platinum or nickel or the aluminium or the copper of 0.8 millimeters thick or the skin material that scribbles catalysis material according to hydromechanical thin-wall effect and makes the cavity of cross section for thin flat, so that liquid fuel enters very fast vaporization when transforming the chamber, the reaction of generation catalytic conversion, and produce thin-wall effect, make air-flow unimpeded.The conversion chamber of thin flat be close to transform the furnace wall, combustion chamber outer or in, or bell is inside and outside, or is suspended in the conversion combustion chamber.The outlet in conversion chamber connects platinum or nickel or the aluminium or the copper of thin straight warp with the casing coupling joint equally or scribbles the appendix of catalysis material, and the gaseous fuel port of export of pipe is connected on the gas flow control valve.Gas flow control valve is by screw thread or be weldingly fixed on the below of combustion chamber, in order to control shower nozzle flame size.The shower nozzle below that transforms in the combustion chamber is placed with pallet, ignites methanol fuel or accepts the methyl alcohol that overflows once in a while in order to hold.The sidewall below that transforms the combustion chamber is the adjustable ventilation window, promptly utilizes the overlapping degree of the row of one on ectonexine concentric circles window to regulate aflame air intake (oxygen) amount.In addition, pilot fuel syringe and igniter are contained in the front portion of stove, so that can inject pilot fuel at any time, igniting when using kitchen range.When using the utility model Carbinol stove, in pallet, inject ignite methyl alcohol or pilot fuels such as ethanol or gasoline by syringe earlier, press igniter simultaneously and light, the initial temperature of methyl alcohol vaporization, generation catalytic reaction is provided.Then, open the switch on the liquid reserve tank, liquid fuel is pressed into woven hose, enters single-pass or multiway valve (or joint) after filtering through filter, flows to the kitchen range eye.The liquid fuel that flows to the kitchen range eye is introduced into the conversion chamber of thin flat.Owing to transform chamber preheating, flow to the methyl alcohol that the transforms the chamber concurrent living catalytic reaction of vaporizing, change into gaseous fuel.After just entering the methyl alcohol vaporization that transforms the chamber, methanol steam generates carbon monoxide, hydrogen and water vapour under the effect of catalyst platinum or nickel or aluminium or copper etc., and heat absorption.This reaction, along with the carrying out of burning, temperature raises, and pressure reduces, and will carry out towards the direction that helps generating carbon monoxide, hydrogen G﹠W.Cleaning, safe gas fuel that the event reaction generates can be through the shower nozzle in the appendix input conversion combustion chamber, burnings.Simultaneously, the size of gas regulation valve regulation shower nozzle flame.Behind the gas fuel combustion that shower nozzle penetrates, transform the place, chamber because the flare of shower nozzle ejection can be mapped to, thereby kept the conversion reaction temperature that transforms the chamber again automatically, burning is constantly continued, flame is constantly by the bell crater ejection that transforms on the combustion chamber.The flame of ejection is through measuring, and the thermal efficiency is the tallest and the biggest in 75%; Combustion heat value is up to 11000 kilocalories.

The advantage of the utility model Carbinol stove is conspicuous, it has not only developed the fresh fuel that the first alcohol and water mixes, a large amount of industrial chemicals have been saved, and improved environmental pollution, and thermal efficiency height, the combustion heat value height, in addition, air pressure in the container in the utility model is lower, and is seldom dangerous.In addition, the Carbinol stove cleaning before not igniting, nontoxic, easy to use, durable, easy to manufacture.Therefore, this is a kind of popular kitchen range.
